RT5112A
Smart Power-Management Integrated Circuit for Camera
Module Application
General Description
The RT5112A device is a smart power management IC
which includes two low-quiescent-current HCOT Buck
converters and four high PSRR low dropout regulators
(LDO). One can control the channel power sequence,
output voltage level and DVS slew rate by setting registers
via I
2
C interface. The output voltage OVP/UVP, OCP and
OTP protection are built in the RT5112A. The RT5112A is
available in a WL-CSP-25B 2.2x2.3 (BSC) package.
